Type IIn supernovae at z ~ 2 from archival data
J. Cooke, M. Sullivan, E. J. Barton +4
Supernovae have been confirmed to redshift z ~ 1.7 for type Ia (thermonuclear detonation of a white dwarf) and to z ~ 0.7 for type II (collapse of the core of the star). The subcla…
Probing the Epoch of Reionization with the Lyman Alpha Forest at z~4-5
Renyue Cen, Patrick McDonald, Hy Trac +1
The inhomogeneous cosmological reionization process leaves tangible imprints in the intergalactic medium down to z=4-5. The Lyman-alpha forest flux power spectrum provides a potent…
Constraining dust and color variations of high-z SNe using NICMOS on Hubble Space Telescope
S. Nobili, V. Fadeyev, G. Aldering +24
We present data from the Supernova Cosmology Project for five high redshift Type Ia supernovae (SNe Ia) that were obtained using the NICMOS infrared camera on the Hubble Space Tele…
Over half of the far-infrared background light comes from galaxies at z >= 1.2
Mark J. Devlin, Peter A. R. Ade, Itziar Aretxaga +26
Submillimetre surveys during the past decade have discovered a population of luminous, high-redshift, dusty starburst galaxies. In the redshift range 1 <= z <= 4, these massive sub…
Mid-IR Luminosities and UV/Optical Star Formation Rates at z<1.4
Samir Salim, Mark Dickinson, R. Michael Rich +15
UV continuum and mid-IR emission constitute two widely used star formation indicators at intermediate and high redshifts. We study 2430 galaxies with z<1.4 in the Extended Groth St…
IRS Spectroscopy and Multi-wavelength Study of Luminous Star-forming Galaxies at z~1.9
J. -S. Huang, S. M. Faber, E. Daddi +24
We analyze a sample of galaxies chosen to have F24>0.5 mJy and satisfy a certain IRAC color criterion. IRS spectra yield redshifts, spectral types, and PAH luminosities, to which w…
